4 ENVIRONMENT indr Cooling System The Revolutionary Integrated Noise and Dust Reduction Cooling System The highly airtight engine compartment and the offset duct contribute to noise reduction. The indr filter fitted in front of the cooling system ensures easy cleaning. The indr system on the SR Series mini excavators features air intake at the front of the machine and air exhaust underneath. It functions in the same way as the indr System on the SR series Heavy machines. Ultimate Low Noise KOELCO s exclusive indr Cooling System delivers amazingly quiet operation. Sound Power Level 93 d Visual Checking and Easy Cleaning ecause the indr filter removes dust from the intake air, cooling components stay dirt-free and do not require regular cleaning. The indr filter itself can be easily removed and cleaned without the use of tools. indr Filter The stainless-steel filter is extremely effective against dust, with 30-mesh wave-type screen that removes tiny dust particles from the intake air. indr Filter locks Out Dust Outside air goes directly from the intake duct through the indr filter for dust removal. 30-mesh means that there are 30 holes formed by horizontal and vertical wires in every square inch of filter. 3

6 PERFORMA NCE Fuel Economy and Digging Power Solid Digging Performance Assured Pump Flow and Pump Pressure Pump flow of 38.4 L/min for SK30SR and SK35SR and 28.8 L/min for SK28SR, and pressure of 23.0 MPa (relief valve setting), maintain ample power. Integrated-Flow Pump System The instant the machine begins to dig extra output from the third pump (which otherwise powers the swing and dozer circuit) is directed to the arm circuit and boom circuit (raise) for added power. This ensures fast and smooth arm and boom raising operation even under heavy loads. Left Travel Right Travel Dozer oom Arm Swing Energy Conservation Mode The machine is equipped with S mode, which lowers fuel consumption by up to 25 % over previous models. One Touch Deceleration The machine features one-touch deceleration. It allows easy switching to an idling state, reducing the fuel consumption while the machine is at rest.and also, the deceleration select switch is provided on the control panel. Deceleration switch Travel Power Large Capacity Travel Torque The large capacity travel torque enables the machine to perform spin turn in low mode even when the dozer is pushing a heavy load. Automatic Two-Speed Travel An automatic shift function ensures smoother, more efficient travel on worksite. When the High mode is selected, the travel system will automatically shift to Low mode whenever the load or climbing grades requires more power. Travel Switch The travel lever is fitted with a button for easy shift up. Digging ucket oom Swing Engine No.1 Pump No.2 Pump No.3 Pump Deceleration select switch Powerful and Efficient Dozer Performance Dozer-lade Shape Kobelco's unique blade design forms the earth into an arc, that always falls in front of the blade. This prevents earth falling behind the blade so only ''one pass'' is needed. Hydraulic Pilot-Controlled Dozer Operation Lever The dozer lever features hydraulic pilot control for precise handling. 5
